Lynred to show smallest thermal imaging sensor
Infrared sensor specialist Lynred will demonstrate a prototype longwave infrared (LWIR) 8.5 µm pixel pitch sensor during AutoSens Europe, an international event for automotive engineers, in Barcelona, Spain, October 8 – 10, 2024.
The 8.5 µm pixel pitch technology is claimed to be the smallest infrared sensor candidate for future Automatic Emergency Braking (AEB) and Advanced Driver Assistance Systems (ADAS).
The prototype, featuring half the surface of current 12 µm thermal imaging sensors for automotive applications, will enable system developers to build much smaller cameras for integration in AEB systems.
Following a recent ruling by the US National Highway Traffic Safety Administration (NHTSA), AEB systems will be mandatory in all light vehicles by 2029. It sets tougher rules for road safety at night.
The NHTSA sees driver assistance technologies and the deployment of sensors and subsystems as holding the potential to reduce traffic crashes and save thousands of lives per year.
The European Traffic Safety Council (ETSC) also recognises that AEB systems need to work better in wet, foggy and low-light conditions.
Thermal imaging sensors can detect and identify objects in total darkness. As automotive OEMs need to upgrade the performance of AEB systems within all light vehicles, Lynred says it is preparing a full roadmap of solutions set to help achieve this compliance.
Currently the company gearing up for high volume production of its automotive qualified 12µm product, to enable Pedestrian Automatic Emergency Braking (PAEB) systems to work in adverse conditions, particularly at night, when more than 75 percent of pedestrian fatalities occur.
